Hi,

see the following code

<br />
m_wndStatusBar.GetPaneInfo(1, ID, Style, width);<br />
Style = SBPS_NORMAL;<br />
width = 500;<br />
m_wndStatusBar.SetPaneInfo(1, 0, Style, width);<br />

In this example you get the style and width of the second pane, change the attributes and set the new attributes.
If you use the index, you don't need the ID.

Regards
Frank

crash? .. ok

now we need some more information:
- which function crashes and possible at which position internally
- the exception message
- if possible the error code (e.g. DWORD GetLastError() ), maybe use a try-catch(...)-block.

I'm trying to work with the mciSendString, but it's new to me. I've not seen it mentioned in any of the books I have. What's it used for?
Tanks!!!!!

Platform SDK: Windows Multimedia

MCI
The Media Control Interface (MCI) provides standard commands for playing multimedia devices and recording multimedia resource files. These commands are a generic interface to nearly every kind of multimedia device.

The mciSendString function sends a command string to an MCI device. The device that the command is sent to is specified in the command string.

Example in Platform SDK Doc:

DWORD PlayFromTo(LPSTR lpstrAlias, DWORD dwFrom, DWORD dwTo) 
{ 
    char achCommandBuff[128]; 

    // Form the command string.
    wsprintf(achCommandBuff, "play %s from %u to %u", 
        lpstrAlias, dwFrom, dwTo); 

    // Send the command string.
    return mciSendString(achCommandBuff, NULL, 0, NULL); 
}

Are you using the C libraries, STL, MFC or Win32? You need to be more specific in the question.

how to use Cimagelist to the bmp images?

allenhu30-Jul-03 14:50

allenhu

30-Jul-03 14:50

i have a couple of bmp images. each image is 24*32 unit and all the images make up a stripe. The stripe image's ID is "IDB_ADDRESS". Now i want to use a
CImagelist to manage these images. i codes like this:

m_ImagList.Create(IDB_ADDRESS,24,1,RGB(0,0,0));
IMAGEINFO m_sImageInfo;
m_ImagList.GetImageInfo(2,&m_sImageInfo); // i want to get the no.3 image
m_BtImage1.SetBitmap(m_sImageInfo.hbmImage); // i want to set the no.3 on the
//button

the m_BtImage1 is a CButton control object which has been set the "BS_BITMAP"
But there is nothing on the button,why?

Connecting to MySQL using VC++

I'm trying to use VC++ to connect to MySQL. To do this, I have use MFC to do it. Initially it was easy when i was using the form that they have created for me. But when I insert my own form/dialog, I can't seems to see the database field for me to map it. Any idea why is it so?
Also is it better for me to use ATL MyOLEDB??

How to change Combobox style at runtime?

Andrew Allen30-Jul-03 14:46

Andrew Allen

30-Jul-03 14:46

My MFC app is using comboboxes with the CBS_DROPDOWN style (i.e. edit control + drop list). The combos are defined in a dialog template. I want to be able to switch these to CBS_DROPDOWNLIST style (i.e. static control + drop list).

My difficulty is that I need to change the style AFTER the comboboxes have been created.

(How) can this be done?

Hi Eugene,

I just tried your suggestion, but it doesn't work.

My combobox is derived from CComboBox, I have a member function to do the switch

void CMyComboBox::MakeStatic()<br />
{<br />
    VERIFY(ModifyStyle(CBS_DROPDOWN, CBS_DROPDOWNLIST));<br />
}

I call MakeStatic() after the combo has been created, but immediately before I load the combo. The ModifyStyle() call returns TRUE - the VERIFY doesn't generate an error. I also tried ModifyStyleEx(), just in case, but it doesn't work either Confused | :confused:

I've had this problem myself. What I did was create TWO combobox controls, one a dropdown and the other a dropdown list, and placed them right on top of each other. I used some other control to determine the state I wanted the "combo" in, and showed/hid the appropriate one.

Actually, I had this problem with CListBox. You can't change its selection style at runtime, either.

Yep, I'm convinced ModifyStyle() doesn't work after the control has been created. I just found this article talking about Listboxes,
http://www.codeproject.com/combobox/listbox_tut.asp[^]
...
Changing List box Styles at Runtime
It is not possible to change these styles at runtime even though ModifyStyle() may give the impression it does. If you want turn the Sort style on and off for example it is best to construct the List box by calling new and Create then deleting it and creating a new one when the style is to be changed. Alternatively you can have 2 List box superimposed and hide the one with the incorrect style.

I already thought about overlapping two controls, but I have about 10 in my dialog and at the time it seemed messy in the dialog template. Looks like that's what I'll do.

thanks for your help!
